Hi PerlMonks,

I need to process the elements of a hash into a string. This so that the string can be used as a named parameter call in a method.

Given below is a sample hash 

$VAR1 = [
          {
            'description' => '$description',
            'new-role-name' => '$new-role-name',
            'role-name' => '$role-name',
          }
        ];

This needs to be processed into : "description => $description, new-role-name => $new-role-name, role-name => $role-name" The code that i've written : 
while(my ($param_key, $param_value) = each(%{$args->{parameter_set}}))
+ {
                $param_string.= "$param_key => $param_value,";
        }

print "\n$param_string\n";

[download]
gives the output 
"description => $description, new-role-name => $new-role-name, role-na
+me => $role-name,"

[download]

What's not correct in the output above is the comma at the end of the string.How do i correct this ?

Thanks in advance!
